Myofibroma is a benign, soft tissue neoplasm that predominantly affects infants and young children. Most occur in the skin or subcutaneous tissues, with a predilection for the head and neck regions. We describe the magnetic resonance (MR) imaging and histophathologic findings of a rare case of intramuscular myofibroma of the right deltoid in a healthy 30-year-old male. MR imaging revealed a well-circumscribed intramuscular mass, with isointense signal on T1-weighted images, hyperintense signal on T2-weighed images, and a "target-sign" with peripheral rim enhancement after gadolinium administration. The lesion was surgically excised with no complications, and the histopathologic analysis revealed the typical morphologic and histochemical markers of a myofibroma. We conclude that, although rare, myofibroma can be considered in the differential diagnosis of adults with lesions the above signal characteristics. • Benign neoplasms of soft tissues with myofibroblastic differentiation • Historically a pediatric illness, peak before age 2; adult cases solitary and benign • Mostly sporadic; some congenital cases linked to PDGFR-beta and NOTCH3 genes. • Intramuscular myofibromas rare; common locations skin/subcutaneous and head & neck • Enhancing iso- to slightly hyperintense on T1 and hyperintense on T2; "target sign" [ABSTRACT FROM AUTHOR] |
